CHARLES ADAM SGHENKEL, OF WABASH, INDIANA.

VEHICLE-TIRE.

Specification of Letters Patent.

Patented Mar. 26, 1912.

Application filed September 3, 1910. Serial No. 580,291.

To all whom it may concern Be it known that I, OHARLns ADAM SOHENKEL, acitizen of the United States, and a resident of Wabash, in the county ofWabash and State of Indiana, have invented certain new and usefulImprovements in Vehicle-Tires, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to certain novel improvements in airless tires.

The primary object of my invention is to provide a comparativelyinexpensive cushion tire, which will practically possess all theelasticity and resilience of an air inflated tube, without beingsubjected to the possibility of becoming useless through a puncture.

A further object is to provide a cushion tire including a tube having anaugmented tread and coupling, and a spring element tending to keep thetire distended and elastic.

lVith these and other objects in view the present invention consists inthe combina-.

tion and arrangement of parts as will be hereinafter more fullydescribed and particularly pointed out in the appended claim, it beingunderstood that changes in the specific structure shown and described,may be made within the scope of the claim, without departing from thespirit of the invention.

In the accompanying drawings forming a part of this specification, andin which like numerals of reference indicate similar parts in theseveral views :-Figure 1, shows a side elevational view of a tire withportions broken away, embodying my invention. Fig. 2, shows a brokenview disclosing the coupling. Fig. 3, shows a fragmentary view throughthe coupling. Fig. 4, shows a top View of the coupling, while Fig. 5,shows a sectional view of the tire.

In my present invention I provide a tire especially adapted to be usedin connection with touring cars, motor cycles and vehicles employed inroad and country travel.

The numeral, 1, indicates a tube tire body which has its two ends fittedinto two draw or coupling collars, marked 5 and 10. The draw or couplingcollars are hollow, as shown in Fig. 3, to snugly receive the ends ofthe tube, 1. In order to insure these draw collars being securely heldin juxtaposition and in alinement, I provide the collar, 5, with theannular groove, 11, within which groove the projecting flange, 12,snugly fits, this flange projecting from the collar, 10, as shown inFig. 3. The tube, 1, is held to the collars by means of the screws, 15.

As shown in the drawings, each draw collar upon the side is providedwith a depression, within which depressions are located the screw eyes,6. Each collar has two sets of depressions, as is shown for instance inFig. 5. Threading into the screw eyes, 6, is a screw, 16, having theoperating handle, 7, this screw, 16, having its ends threaded inopposite directions, so that in turning same, the stem willsimultaneously thread into the two screw eyes, 6. Two such screws, 16,are used and by means of these, the collars are securely held together.These collars are made of extremely thin material and the depressionformed by means of the inwardly curved metal, 18, performs a doublefunction, in that the collars can be compressed within certain limits.Held within the tube, 1, is a coil spring, 4, this spring being made ofwire square in cross section, so that the spring presents a flat surfaceto the tube, 1, as is shown in Fig. 1. This spring is of uniformconstruction throughout, the said construction being clearly exposed inFig. 1 of the drawln s.

uitably secured to the tube, 1, is a tread, 20, this tread beingcrescent shape, as is shown in Fig. 5. The tread, 20, is in the form ofa complete annulus, and is vulcanized or otherwise secured to thetube, 1. The ends of the tube, 1, however, are not vulcanized or securedto the tread, 20, so that these ends can be removed from below thetread, permitting the insertion or removal of the coil spring, 4. Thecollars, 5 and 10, are provided with the threaded openings, 23, arrangedto receive suitable screws, 24., by means of which a cap plate, 25, issecured to these collars, in the manner shown in Fig. 1.. The spring, 4,is made of any suitable material and is of such a diameter as toresiliently carry the maximum load likely to be placed upon the ve hicleto which the tire is secured.

From the foregoing it will be noticed that after the collars have beenforced under the,

tread, 20, the same can not become casually displaced. The tread, 20,being continuous and the collars, 5 and 10, being resilient, noappreciable jar is felt when the collars come at the lowest point of.the wheel.

An airless tireconstructed according to my invention is simple andinexpensive in construction, and both durable and efficient inoperation, and the adjustment of the collars and the insertion of thespring may be made with ease, accuracy, and despatch.

Having thus described my said invention, what I claim as new and desireto secure by United States Letters Patent, is

The combination with a tube of two hol- I low resilient collars, each'collar having .op-

positely disposed inwardly directed indenta- 15 for co-action'with saidflange, and a tread 20 partly secured to said tube.

In testimony whereof, I aflix my signature in presence of two witnesses.
